I guess I’m assuming “economic apocalypse” means “fall of the nation state concept as we know it.” since that is the lynch pin for economic trade.
Business operations as a whole are so reliant on the legal rails, like it or not, they’d have to fail spectacularly to create “economic apocalypse” to my mind.
I forget some people see run of the mill loss of wealth status as akin to loss of life. So perhaps apocalypse to them means going from $100 million in wealth to merely $10 million, but the social foundations that support that wealth largely remain intact
